Jelani McCoy has been the quintessial journeyman end-of-bench type player throughout the NBA, but the reason he keeps getting called back to the NBA, despite his ever-advancing age (currently 31), is because he's always had very solid athleticism/mobility for a big man, and he's a solid rebounder/shotblocker sort of guy who doesn't mind doing the dirty work. He really seems to be making a real push back into the NBA--looking at his #'s with our sister team the LA D-Fenders, he showed some sparks of skill that he seemed to have lacked back when he was a 24 year old with us; in 30.3 mpg, he averaged 11.2 ppg, 7.9 rpg, 3.3 apg, 2.1 bpg on top of 2.0 fouls per game. Scale those to NBA #'s and taking into account the vastly greater competition, it's safe to say that he's not a scorer in the NBA (despite shooting 69% from the field), he's probably a slightly above average rebounder and he's a very solid shotblocker; two surprising attributes there is that he seems to have reigned in his foul problems (2 fouls in 30+ mpg is very solid for a big man in any league; he averaged 2 fouls per game alone in 14 mpg throughout his NBA career) and he seems to show surprisingly good passing ability (3.3 apg--although as evidenced with his 2.6 tpg, he's probably forcing the issue being a vet in the youth's league--getting more touches).
Thumbnail sketch of how his game is like today: probably still the same guy--will score the garbage baskets, get a few rebounds, block a few shots, but with less foul trouble and perhaps slightly better passing ability. An improvement from where he was seven years with us, but at the end, still a scrub--at his age, he is what he is, and seems to be a forever fringe player in the NBA who will only be called upon for backup big insurance. Frankly, I'm more in favor of the young guys, because McCoy--we know what he is and he can only do so much in the NBA--and because I'm more enamored with Giles' potential and/or with Mbenga's current contributions.
EDIT: I took the liberty of finding Elton Brown's NBDL stats prior to his joining us for the SPL/training camp last year in 2007, and in 32.6 mpg he put up 18.4 ppg, 9.6 rpg, 2.1 apg, 0.5 spg, and 0.3 bpg; obviously Jelani shows much better all-around stats, but considering that Elton's game is predicated on scoring and rebounding, and considering the fact that he couldn't even cut our team, that really shows how much of a far shot Jelani has of making our team (being a worse rebounder and far worse scorer, although better passer/shotblocker than Brrown).
